Shuts down the system And turns off the power. The system must support the power-off feature.

· lpMachineName
Points to the null-terminated string that specifies the network name of the computer to shut down. If lpMachineName is NULL or points to an empty string, the function shuts down the local computer.

· lpMessage
Points to a null-terminated string that specifies a message to display in the shutdown dialog box. This parameter can be NULL if no message is required.

· dwTimeout
Specifies the time (in seconds) that the dialog box should be displayed. While this dialog box is displayed, the shutdown can be stopped by the AbortSystemShutdown function.
If dwTimeout is not zero, InitiateSystemShutdown displays a dialog box on the specified computer. The dialog box displays the name of the user who called the function, displays the message specified by the lpMessage parameter, and prompts the user to log off. The dialog box beeps when it is created and remains on top of other windows in the system. The dialog box can be moved but not closed. A timer counts down the remaining time before a forced shutdown. If the user logs off, the system shuts down immediately. Otherwise, the computer is shut down when the timer expires.
If dwTimeout is zero, the computer shuts down without displaying the dialog box, and the shutdown cannot be stopped by AbortSystemShutdown.

· bForceAppsClosed
Specifies whether applications with unsaved changes are to be forcibly closed. If this parameter is TRUE, such applications are closed. If this parameter is FALSE, a dialog box is displayed prompting the user to close the applications.

· bRebootAfterShutdown
Specifies whether the computer is to restart immediately after shutting down. If this parameter is TRUE, the computer is to restart. If this parameter is FALSE, the system flushes all caches to disk, clears the screen, and displays a message indicating that it is safe to power down.
